Even when you have doubts, take that step. Take chances. Mistakes are never a failure - they can be turned into wisdom.

It's not necessary to fear the prospect of failure but to be determined not to fail.

I can accept failure, everyone fails at something. But I can't accept not trying.

It is not a disgrace to fail. Failing is one of the greatest arts in the world.

Failure happens all the time. It happens every day in practice. What makes you better is how you react to it.

My great concern is not whether you have failed, but whether you are content with your failure.

Develop success from failures. Discouragement and failure are two of the surest stepping stones to success.

You can't be afraid of failure and you can't be afraid of success, because either one gets in the way of your work.

Failure is nature's plan to prepare you for great responsibilities.

Success is never final, failure is never fatal. It's courage that counts.
